Do a search on the web for the Miyawaki Beach Popper; Jack Gartside's Gurgler is also a favorite surface pattern. These surface patterns are great for searching, if there are fish (coho or sea-run cutthroat) around they'll usually show themselves by at least making a pass at it.

While resident coho feed heavily on baitfish, they also eat large numbers of amphipods (a tiny relative of the sand flea) and euphausids (a small shrimp-like invertrbrate; krill) and simple imitations of these will often be effective when the fish show no interest in baitfish patterns.
